Gunicorn ImportError: Aucun module nommé application

Question

salut Je suis ce tutoriel https://semaphoreci.com/community/tutorials/dockerizing-a-python-django-web-application sur la façon de déployer sur docker un projet Django, à un moment donné, vous devez commencer à utiliser gunicorn mon start.sh est comme ça.

#!/bin/bash 

#start gunicorn processes 

echo "starting gunicorn for wrappers" 

exec gunicorn sparqlwrapper.wsgi.application --bind 0.0.0.0:8000 --workers 5 

mais quand je lance le start.sh je reçois cette erreur

quand je lance le projet avec python manage.py runserver 0.0.0.0:8000 il ne fonctionne donc il doit être gunicorn lui-même

Answer 1

L'objet application n'est pas un module; vous devez utiliser un colon, pas une période, pour le séparer du module, il est.

exec gunicorn sparqlwrapper.wsgi:application --bind 0.0.0.0:8000 --workers 5
